Expounds the basic knowledge of wind power generation and related technical characteristics, and introduces the VSC-HVDC application in electric energy transportation of wind farms and the research status in our country. The technology solves the current problem of long-distance high-power electric energy transportation of wind farms. Through the analysis of the VSC-based HVDC features and basic principle, indicates that the technology is currently ideal transmission way of wind generation and grid connection. The simulation on VSC-HCDC by Matlab/Simulink software shows that it well solves the current problem of remote electric energy transmission of power farms.
